Abstract

A vehicle suspension system which uses a road surface monitoring device (1) and a pneumatic piston / coiled spring coaxial suspension assembly (2) connected via a control box which actively adjusts the pitch of the suspension to counteract a roads uneven surface. The suspension assembly is connected to the vehicle body via a joint, allowing the connecting piston to hinge as its length is altered. Wrapped around each piston is a coiled metal spring. As the pistons are made to change their length by the control unit, so the pitch of the suspension also changes.

Description

Predictive Vehicle Suspension This invention relates to a vehicle suspension system which uses a road surface monitoring device and a pneumatic piston/coiled spring coaxial suspension assembly connected via a control box which actively adjusts the pitch of the suspension to counteract a roads uneven surface.
Current suspension systems found in motorised vehicles consist primarily of a coiled metal spring, which partially absorbs the shock wave produced by bumps in the roads surface. These systems suffer from the disadvantage that they do not forward plan their behaviour when approaching a bump. On striking the bump, a shock wave is then felt by the driver and passengers.
Accordingly, this invention provides a suspension system comprising of a road surface monitoring device mounted a set distance forward of a given tyre and connected via a control box to the suspension assembly. The suspension assembly consists of a set of pneumatic pistons each encased in a coiled metal spring.
The input device detects pits or bumps in the roads surface soon to be visited by the vehicles tyres and relays this information to the control box. The vehicles speed is also relayed to the control box so that the time until the vehicle tyres will hit a particular pit or bump in the road can be calculated by the control box.
The control box then instructs the pneumatic pistols to elongate or shorten on cue and by a set amount so that pitch of the suspension (i. e. the distance between the vehicle body and the wheel axle) changes by a distance equal to that of the depth or height of the obstacle in the road. The net effect is to cancel out the pits and bumps in the roads surface so that a smoother journey ensues for the driver and passengers.
A preferred embodiment of the invention will now be described with reference to the accompanying drawings; Figure 1 This shows side view of the key feature of the predictive vehicle suspension system.
* Figure 2 This shows in more detail the suspension assembly.
Figure 3 This shows in more detail the pneumatic piston/coiled spring coaxial suspension component.
As shown in Figure 1, the key features of this invention are the input device (1) and the suspension assembly (2). The suspension assembly consists of a set of pneumatic pistons each encased in a coiled spring Figure 2 shows in detail, the components of the suspension assembly (2). The suspension assembly is connected to the vehicle body via a joint (3), which allows each connecting piston (4) to hinge as its length is altered. Wrapped around each pneumatic piston is a coiled metal spring (5). The ends of the pistons connect at the wheel axle (6). As the pistons are made to change their length by the control unit, so the pitch of the suspension also changes.
Figure 3 shows a detailed diagram of the pneumatic piston/coiled spring coaxial suspension component. The key features to note, are the positions (7 & 8) at which the suspension spring joins the piston shaft (9), either side of the pistons pneumatic chamber (10).
